(b) water and oxygen
(c) ozone and oxygen
(d) water and carbon dioxide
(c) ozone and oxygen
Elemental oxygen is normally found in the form of a diatomic molecule. However, in the upper reaches of the atmosphere, a molecule containing three atoms of oxygen is found, which is called as ozone.
The presence of oxygen in the air (atmosphere) is essential for the following:
1. The life processes such as respiration, in all living organisms.
2. Combustion of fuels.
The presence of ozone in the air (atmosphere) is essential for the following:
1. Ozone is a gas in the atmosphere that protects everything living on the Earth from harmful ultraviolet (UV) rays from the Sun.
